pplication--led Hey 13, 1912f. Serial No. 767,291. v 1

To all-'whom z'tmay concern 'l Be it known that I, AXEL' EKs'rnoM, a citizen of the United States, residing at Ballston Spa, in the county of Saratoga and State of- New York, have invented certain new and useful Improvements 'in Railwav-Cars, the following being a full, clear, and exact disclosure ofthe one form of' my Eer a detailed description'ffoflthe present form of my invention, reference may be had' to the following speeificationgand tothe aob companyingdrawings forming a part there of, .in which, l

Figure 1 is a side elevation of myicar; Fig. 2 is a side elevation and Fig. 3 ai of the under framing forming atruclr.-

My invention relates to cars particularly;

invention which I at present-deean'prefer-l adapted for street service or other situations?V involving severe corners. l, It consists in a four-wheel depending body portion with" 'd 'doors` therein included between the-two car axlesand extended endsl overhanging-the; side axles. This arrangement is to be contrasted with side-door cars supported on swivel trucks .at each end, in that my construction permits of a deep and short framework be' tween the axles which takes the supporting strain, While the extended overhangmg lends can' be comparatively light. Thus Iam enabled to save in the amount of steel required for the car and also in weight.

. Turning to the drawings, A represents the car body and B the central depending portion thereof between the axles ai w with the side doorsD Dtherein and the car sides projecting down outside the wheels.41 Thedoors open into a de ressed central space within the car from w ich one or more steps lead to the floor level ofthe extended ends. The

car body is shown as re'stin on a truck .frameg This comprises the si e-bars E and F depressed below the depending portion B and-jointed' on a horizontal axis at e and f respectively: and also jointed at 'those points to blocks E1 and F1 which bear against the under side of the car body preferably through interposed sp'rngs.' The side bars` are connected by end bars G, G1,- alsomby cross bars H and H1, while the cross bars K, K1 receive between them thede ndin portion B of the car body and race-"1t against the axles on either side Ythrough-the which embrace-the journal boxesonthe respective axles. Four springs S on the corners ofthe frameaoresaid support the car body while .the propelling motors .M are .spring supported as shown on the cross bars centered on the axles a', so as to be supported' outside of the said axles respectively and geared thereto. The above described of the overhanging ends.

Brakes J are provided which bear on the inside surfaces of the wheels W between those wheels and t-he depending portion B of the-car body.

Besidethe `advantage mentioned heretofore my construction tends to bring the cenv-terio'f gravity of the car close to the 'wheels and axles-to which both the starting andv stpphg forces arehapplied. This avoids a di erence inpressure of the wheels on the .track as well as jarring of the car body at starting and stopping. -I also put all of the Weight on the driven axles with only .two motors while the extended ends permit the use of a car as lon as those which ordinarily .i'require two swive trucks 'which' must have fourmotors if all the axles are to be driven.

Other desirable features will' be apparent.

What I claim as new and desire to secure by Letters Patent is:

1. A four-wheel railway-car, having a 'depending portion between the'two car-axles provided with side doors and extended ends overhanging said' axles.

V2. A four-Wheel railway-cai; having a depending portion between the two car axles provided with side doors and extended overhanging ends,'the said depending portion being braced longitudinally against the respective axles.

pending port-ion between the two car axles provided with side doors', extended ends overhanging the said axlesand propelling motorssupported outside of and .geared to the said axles respectively.

pendingpor'tion between the two car axles provided wlth side doors, extended ends supported outside of andgeared to said axes respectively and brakes between said depending portion and the wheels, whereby side frames and the pedestals F2.
